Il Gran Caffè di Giuseppe Damiani Almeyda
2015
Il testo affronta lo studio di un’opera giovanile di Giuseppe Damiani Almeyda (1834-1911), figura di spicco del panorama architettonico in Sicilia tra la seconda metà dell’Ottocento ed i primi del Novecento. Il progetto del Gran Caffè, vincitore di prestigiosi riconoscimenti, anche se realizzato quando Damiani non era ancora trentenne, risulta molto maturo e segna una tappa importante nella formazione dell’architetto. Se ne ritroveranno richiami progettuali nel Politeama, edificio a cui il suo nome è legato, e in una grandiosa opera didattica, la Scuola Italiana di Architettura Civile, che, purtroppo, non è mai stata pubblicata. I disegni originali, a matita, inchiostro ed acquerello su car…
Physical and mechanical properties of sustainable hydraulic mortar based on marble slurry with waste glass
2021
This paper aims to propose and characterize a sustainable hydraulic mortar entirely obtained by the reuse of waste materials, with marble slurry coming from quarries in the north-western Sicily and glass powder coming from a waste collection plant in Marsala (Province of Trapani). The first was used as raw material to produce the mortar binder by a kilning and slaking process, while the second was used as a pozzolanic additive. The chemical and morphological characterization of the marble slurry was done by XRD, FTIR, STA and SEM analyses. Glass powder was analyzed through particle size distribution measurements, XRD and standard pozzolanic tests. Hydraulic mortars constituted by slaked lim…
The Reliability and Validity of Scores from the Children’S Version of the Perception of Success Questionnaire
1999
Recent research into achievement motivation in sports has focused on goal orientation theory, according to which task and ego goal orientations manifest themselves in achievement contexts and may have different cognitive and affective outcomes. The present study analyzed the reliability and validity of scores on the children’s version of the Perception of Success Questionnaire (POSQ-CH). The participants were 557 14-year-old Finnish male soccer players. Because the Task Orientation and Ego Orientation subscales were found to be orthogonal, we applied confirmatory factor analysis to the task and ego orientation items separately to evaluate the reliability and validity coefficients of the it…
Gothic architecture: technologies and construction site management
2018
During the Gothic times, between the XIV and the XV centuries, depending on the location, many interesting developments occurred. Such an architectural movement moved towards completely new directions and ideas if compared to the previous centuries’ construction. First of all the concept of the space, inner or external, that became highly polycentric and driven to the highness and to a certain dematerialization of the solids. Such a novel vision was often related to the new religious fervour of that time. Some examples are the reduction of the masonry’s sections, a massive usage of large coloured glazing, and the creation of light groined vaults. On the exterior, all of that corresponded to…
Un progetto non realizzato: il Gran Cimitero di Giuseppe Damiani Almeyda. Dai disegni di archivio alla ricostruzione tridimensionale.
2016
L’obiettivo di questo studio è la ricostruzione e l’analisi di un progetto non realizzato: il Gran Cimitero di Giuseppe Damiani Almeyda (1834-1911), a partire dai suoi disegni originali, realizzati a matita, inchiostro e acquerello su cartoncino. Il progetto ha vinto la medaglia d’oro sia alla Prima Mostra Nazionale di Belle Arti di Firenze, nel 1861, sia alla Mostra di Sicilia di Belle Arti, nel 1863. La ricostruzione del modello tridimensionale è servita per dedurre elementi di interpretazione, quali l’impostazione modulare dell’intera composizione, e viste prospettiche, ombreggiate o renderizzate, elaborate cercando rendere visibili gli spazi immaginati nei disegni originali in proiezion…
Teaching computer language handling - From compiler theory to meta-modelling
2011
Published version of a chapter in the book: Generative and Transformational Techniques in Software Engineering III. Also available from the publisher at: http://dx.doi.org/10.1007/978-3-642-18023-1_14 Most universities teach computer language handling by mainly focussing on compiler theory, although MDA (model-driven architecture) and meta-modelling are increasingly important in the software industry as well as in computer science. In this article, we investigate how traditional compiler theory compares to meta-modelling with regard to formally defining the different aspects of a language, and how we can expand the focus in computer language handling courses to also include meta-model-based…
Economic feasibility study for intensive and extensive wastewater treatment considering greenhouse gases emissions
2013
Economic feasibility assessments represent a key issue for selecting which wastewater treatment processes should be implemented. The few applications that exist focus on the positive economic value of externalities, overlooking the existence of negative externalities. However, wastewater treatment plants (WWTPs) consume a significant amount of energy, contributing to climate change. In this context, as a pioneering approach, greenhouse gas emissions (GHG) have been incorporated as a negative externality of wastewater treatment. Within this framework, this study aims to compare the economic feasibility of five technologies, both intensive and extensive, for small communities. The results sho…
Efficiency improvement of a ground coupled heat pump system from energy management
2011
The installed capacity of an air conditioning system is usually higher than the average cooling or heating demand along the year. So, most of the time, the system is working under its actual capacity. In this contribution, we study the way to improve the efficiency of a ground coupled heat pump air conditioning system by adapting its produced thermal energy to the actual thermal demand. For this purpose, an air conditioning system composed by a ground coupled heat pump and a central fan coil linked to an office located in a cooling dominated area was simulated, and a new management strategy aiming to diminish electrical consumption was developed under the basic constraint that comfort requi…
The Thin bilateral and bipedicled DIEAP flap for axillary reconstruction in hidradenitis suppurativa
2019
Reconstruction after resection of advanced stage hidradenitis suppurativa is currently performed with pedicled perforator flaps, that allow functional reconstruction and preservation of shoulder function. Skin availability is limited by the possibility of closing the donor site primarily. Bilateral cases need to be treated in two stages, since the operation is carried out in the lateral decubitus. In this manuscript the application of bilateral and bipedicled DIEAP flaps to bilateral and extensive cases is presented.Between October 2008 and October 2018, 39 patients were treated for axillary hidradenitis suppurativa. Of these, 11 patients had bilateral reconstruction with bilateral DIEAP fl…
Chirurgische Behandlung des hypoplastischen Linksherzsyndroms
1999
Kinder mit dem angeborenen Herzfehler eines hypoplastischen Linksherzsyndroms haben ohne fruhzeitige chirurgische Behandlung eine extrem ungunstige Prognose. Anhand einer retrospektiven Funf-Jahres-Analyse werden die Moglichkeiten und Ergebnisse der herzerhaltenden palliativen Rekonstruktion dargestellt.
